Before you buy

Check Synology’s current compatibility list for the exact drive, NAS model and DSM version.
Drives are separate purchases. Confirm the exact model and hardware revision in the manufacturer compatibility list.
Keep an independent backup of irreplaceable files. RAID does not protect against every cause of data loss.
